Upgrade to Pro

Unlock Pro.
Two ways to pay.

Send USDC on Polygon to unlock Pro. Try it for 30 days at $14.99, or commit to the annual pass at $99 ($8.25/mo — 45% off the monthly rate). The extension verifies your payment on-chain — no payment processor, no account, no auto-renew.

↺
Already on a pass? Your remaining days stack. Pay for annual mid-monthly and your unused days slide on top — same as a pro-rated discount, handled automatically on-chain. No wasted USDC.

// 30-DAY PASS

4.99 USDC
$14.99 / month · pay once · valid 30 days

Lowest-friction way to try Pro on a real parlay or two. Renew whenever you want — no subscription, no auto-charge.

BEST VALUE · 45% OFF

// 365-DAY PASS

39 USDC
≈ $8.25 / month · pay once · valid 365 days

For active bettors. Pays for itself in ~3 rebalanced parlays. Same on-chain mechanism — set it and forget it for a year.

Rebalances needed to break even on the $14.99/mo cost

Math: a single rebalanced parlay covers a month of access. At $99/year (~$8.25/mo), less than one rebalanced parlay per month breaks even. If you bet bigger or more often, the ratio gets stupid quickly.

(Numbers above are model-based — actual results vary by your slip selection. PolyParlay shows you the sim win-rate distribution so you can verify.)
